supply and maintaining the :water level in a boiler. v i

The objects of this invention are to provide an improved float valve means for the purpose. Objects relating to details and OCOHOIDlQS er construction and operation will definitely appear from the detailed .de-

scription to follow. The objects of themvention are accomplished by thedevices and means described in the following specification. The invention is clearlydefined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawings forming a part of this specification in which:

Fig. I is a detail diagrammatic View of the structure in its relations to a steam boiler, a fragment of which is shown.

Fig. II is a longitudinal'detail sectional view through the float valve structure including the steam chamber thereof.

In the drawings similar numerals of reference refer to similar parts throughout the several views. I

Considering the numbered parts of the drawings by their numerals, 1 is a steam boiler, a fragment only beingshown. 2 is a glass water gauge for showing the water level. 3 is the outer casing including the steam chamber for my improved valve structure, same being provided with a steam tight flanged cover 3. 4: is the connection from the upper part of the steam chamber to the steam space of the boiler, and 5 is the flanged pipe connection from the casing 3 to the boiler connecting below the water line.

Casing 3 extends above the water line and the connection through the pipe 5 to the chamber of the boiler maintains the same water level in the casing 3 as is in the boiler. 6 is the water supply pipe extending through the stufling-box 7 in the end of the casing 3 and connecting at its inner end to the valve casing 8 which is disposed and arranged within the said chamber 3. 9 is the outer chamber of the valve and 10 is the inner chamber the inner chamber being connected to the boiler through the pipe '11 which is arranged to extend centrally of piper) well into the boiler.

Vertically disposed through the casing of the inner chamber 10 is a balanced piston valve 12 fitting accurately in the bores 13 in the walls of the inner chamber. This piston valve is provided with transverse openings let at the top and bottom. In its up position the valve is closed and in its down position the outer chamber 9 connects to the inner chamber 10 and permits the flow of water from the pipe 6 through the valve through the pipe 11 to the boiler.

The valve chamber is provided with a re-a movable top plate 15. A valve stem extends through this top plate and at its upper end is pivoted to lever 18 by transverse pivot 17 and is fulcrumed at 19 at the upperencl of thelink 20 carried on pivot 21 on said top plate15. 22 isthe ball float on the end of the lever 18 which rises and falls with the riseand fall of the water in the said chamher 3.

It will be seen by this arrangement that the pressure is equalized on the valve 8. The pressure of the boiler is maintained within the chamber 3. Water is supplied to the boiler through pipe 6 past the piston valve through pipe 11. The water of the boiler and the said chamber3 is in communication through pipe 5. The water rises in the chamber 3 to the same level as in the boilerand acting upon the float cuts off the supply as soon as the desired predetermined level is reached.

This structure is very simple and effective in its operation and very compact. The parts are readily accessible through there movable cover and all parts are very readily detached and likewise very readily assembled.

It is clear that the structure is capable of considerable variation without departing,

from my invention.

Having thus described my invention what therefrom Withinthe connecting pipe to the water space of the boiler, avalve, the casing of which comprises an outer chamber I for v the purpose specified.

2. Ina control valve structure, the combination of a casing connected by suitable pipes at the upper portion to the steam space and at the lower portion to the water space of a'boiler, a supply pipe leading into the said casing andva delivery pipe leading therefrom within the connecting pipe to the water space of the boiler, a. valve the casing of which-comprises an outer chamber and an inner chamber, a vertically disposed piston valve through bores on the opposite sides of the said central chamber, a

float and connection "within the said casing to control the said valve.) 3. In acontrol valve structure, the combination of a casing connected by suitable pipes at'the upper portion to the steam space and at the lower portionto the water space of a boiler, a supply pipe leading into the said casing and a delivery pipe leading therefrom within the connecting pipe to the c water space of the boiler, a valve the casing of which comprises an outer chamber and an inner chamber, a piston valve disposed through bores on the opposite sides of the said central chamber, a float and connection within the said casing to control the said valve.

4. A control valve structure having an outerzcasing connected to both the steam and water space of a boiler, a water connection disposed through the said casing and water space connectionfor delivering water to the boiler, a balanced piston valve, a float and connection within the said chamber to actuateand control the said valve.

5.'A control valve structure havingan outer casing connected to both the steam and waterspace of a boiler, awater connection disposed through the said casing and water space connection for delivering water to the boiler, and a ball float for controlling said I delivery.

In Witness whereof my hand and seal.
